Annoying problem that prevented comments on blog fixed. Hopefully.

Looks like I've finally fixed a problem that prevented you to comment on my/this blog. It was caused by blogengine.net's TypePadFilter extension that, when unconfigured, was throwing an uncaught exception that was propagated to the user that initiated comment save.
Here is my feedback on the issue. Hopefully the blogengine.net crew will make the posting comment less error prone by embedding all calls to extensions with a try/catch clause.
Anyway, fire comments away - good or bad. And please, let me know if there are still problems.
